PATENT Original application area Au ust 21; 1926, Serial No. 130,615. Divided and this application fiIediApriI 1927. Serial This invention= relates to controls and "locks therefor, and particularly to apparatus for preventing the unauthorized ofan automobile. j L p i This application is a division of "my 'copending applicationSerial No. 130,615, August 21, 1926. i 1

Oneof the objects of the present invention is to providea controller which maybe 10 of the controller to operating position is prevente'd'so long as the key remains in the lock.

Preferably, the controller includes -means for automatically moving the operating tion when "lock. T

, flplications, and-,fwhen applied toan electric A 20 switch, theobjects 'of the invention are ac-' complished" by providing an electric switch with means such as a spring tending to move the movable contact of the switch'to' closed position, a key operated device for releasing th e' sprin and a device whichpermits unlocking theflswitch but prevents completemovement of the switch to closed position "so long as the key is (in the lock. "Consequently, when the key is removed the switch- -willfbeautomatica lly moved by the springl to closed position. i i

A further object of the invention is to pro vide a combined switch and lock comprising separate unitary sub-assemblies, one of which includes an operating member and lock therefor and the other of-which includes; the complete switch. When these sub-assemblies are joined together the operatingmember ofthe switch will be positioned for operation by the operating member of the controller.

A furtherobject of the invention is to provide a unitary ignition coil, ignition circuit switch, controller/for the switchfiand lock therefor including novel features such I as mentioned in the foregoing paragraphs. 1 Further objectsf and advantages of the presentl invention willbe apparent from the following description, reference being bad I "=to the acc'ompanyingi'drawing, wherein a unlocked by theuse of akey, but movement member of the controller to operating posif with i an inwardly extending 'flange 27 which I I engages a shoulder 28 of-xtheguide .24, and:

V v i w The stationary contacts 74 and 75 are adapted to-beengaged by the outwardly extending flange 80 of a metallic, cup-shaped switch operating member 81 which is cated within the tube 77. A spring 82 tends to urge the contact operating member-81 outwardly with respect to the recess 7 6' and tacts 74 and 75 It is therefore apparent actuator 81'Within the tube 77 l The non-conducting endmember 66 is supported by a metallic coil housing'end member 90 whic'hjis" attached at 91. to the coilhousing tube *64'and which is provided- "with ana'perture through whichia portion of the non-conducting member extends as shown in Figs. 2 and 6.- A. case or support-for the switch is provided bythe members 66 and 90 and by a flanged collar 92 core housing tube 64.- The collar 92 has the bolt 41 is in alignment with the recess 42 whereupon the spring 44 will be released 1 which is permanently secured to the metal an outwardly extending flange'93 which is adapted to be secured to' the plate 26 by rivets 94 and rivet studs 95. It is therefore apparent that the parts 66, 90', 92- and '26 will provide a housing for the switch.

Like thecontroller and lock, the V ignition c'oil andswitch m'ay be constructed as'a separate sub-assembly. When'the ,controller and lock sub-assembly 'is united to the sub-assemblies may be readilydis-assembled by shearing oil" the riveted portions in'case "repairs or displacements of-either sub-assembly are desired.

' The studs 95 are provided with tapped its flange 80 into engagement with;the.con

I that these contacts will maintain the contact holes 96 for receivingscrews 97Tby WhlCl1 V of aninstrumentb'oard 98. I l r Theloperation of the controllerr with respect tothe switch will nowube described.

When the controller isin locked position as shown in Fig. 2, the switch contactqflange 80 is'separated from the contacts 74 and 7 5, thereby breaking the circuit of the primary winding of the ignition coil. The fiange SO is spaced from the end wall of the recess 76" the structure may be attached to the back so as to permit, complete movement- Ofutll while at the same time allowing tor 'varia tions in manufacturer? v A; When the key$46 is-inserted in'the cylinder and turned to withdraw the -boltlj4l from the recess 42, theoperating, member 20 will beciautomaticallymoved by the spring I 40 into the-position shown in :Fig. 3, where-1;.

in the locking ,bolt-41i'is'. held in'retracted position; Due to the engagement of the stop with the wall 57 a defining the recess 57, .7

movement of the operating member 20, is

arrested and hence thecontact flange SOcannot: engage the switch contacts 74 and While the keyremains in'the look. This feature compels the car driver to withdraw the key from the lock in order to startthe and the spring 40 will-be released to move the operating member 26 iurther toward the left so that thespring 82, niay move the contact flange intoengagement with the contacts74 and 75. When the operating memberQO has completed-its fullmovement toward the left, and when the contact flange 180has engaged the contacts 74 and 75 there will be a slightspace between therighthand left hand. end-of thehcontact actuator v81. In this way the closingof the switch is assured although there may be some slight variations in manufacture:

" To op en the switch the operatoryhasbuti to push in the operating. member20 until to maintain the operating member in nonoperatlng pos1t1on and the switch 1n open before-the controller can be moved to operating position to renderoperative some essential part of the automobile such as the ignition apparatus. Another feature is that; "the controller may be moved and locked in non-operating position vorthe ignition switch end ofs the non-conducting" tube lr23 andthe v in open position without ,the use of.- a key.
